Hi There, I am an Electrical contractor and I use parallels just to run a windows estimating software package on my Mac. I have to keep making the partiion larger as windows is constantly expanding, if I dont I get loads of error messages due to lack of disk space. I only want to use the estimatimg software and no other windows programmes, how can I delete unwanted files or prevent disk space from being taken up by windows constantly expanding/slowing down parallels ? How can i check which files are taking up all my windows partiton? Or is a virtual machine a mirror image of my mac files just in a windows version? I dont want to use boot camp! Thanks in advance !
